In other embodiments, projection 586 and seal 588 can have other shapes and configurations, corresponding to the shape of a recess 342 an underside of an associated mounting bracket 340. Additional information about flashing, projection shapes, seals and water tight roof attached are disclosed in commonly-assigned U.S. Pat. No. 8,209,914, filed on Oct. 28, 2010, and U.S. Pat. No. 9,134,044, filed on Apr. 21, 2014, the contents of both of which are herein incorporated by reference in their entirety for any purpose.
Flashing 580 may be provided in any suitable length and/or size. Traditionally flashings have been provided in 12-inch lengths. This allows the flashing to extend up underneath a first and second course of shingles creating the area where the flashing is beneath both of these courses called the headlap. This requires a flashing installer to disrupt two courses of composition roofing shingles above a desired installation point and remove nails to allow the flashing to be installed. This installation process has been traditionally accepted and required by roofing manufacturers to maintain the integrity of the roofing watershedding capacity. This requirement is of value when the flashing and mounting brackets are located where two shingles come together called the shingle joint as well as on three tab shingles where there is a keyway between the tabs. With the advent of architectural shingles dominance in the roofing market the intersection of mounts and keyways or shingle joints are dramatically reduced consequently reducing the instances where creating the headlap is of value. In this case, a shorter flashing that only extends up under a single course of shingles is an improvement because the value of not disturbing the roofing material and removing nails outweighs the benefit of creating the headlap. For this purpose, flashing 582 may be provided in a shorter length to provide for a watertight installation. In this regard, the flashing may be installable underneath a single adjacent course of shingles without having to remove nails..
In various embodiments and with reference to FIGS. 6A and 6B, roof attachment system 600 may comprise a rail 690. Rail 690 may have a bottom surface 692 and a top surface 698. Bottom surface 692 and top surface 698 may be substantially parallel to one another. In other embodiments rail 690 may not include a top surface 698 presenting an open channel rail or top surface 698 may not be parallel to bottom surface 692 and may be curved. Rail 690 may also comprise a first side wall 691 and a second side wall 693. First side wall 691 and second side wall 693 may be substantially parallel to one another. In other embodiments side walls 691 and 693 may not be parallel and may not be straight. First side wall 691 and second side wall 693 may be substantially perpendicular to the top surface 698 and bottom surface 692. First side wall 691, second side wall 693, bottom surface 692, and top surface 698 may be operatively coupled together to form a profile of rail 690. In this regard, Rail 690 may generally have a square, rectangular, and/or box profile. Bottom surface 692 may also include first engagement tab 694 and second engagement tab 696 that protrude be on the first side wall 691 and second side wall 693.
In various embodiments, roof attachment system 600 may be configured to receive, support, and retain a rail 690. In this regard, the roof attachment system 600 may define a channel or slot 621 (e.g., a “pop” in slot or a “click” in slot). Channel 621 (e.g., the place defined by the bottom thickness of rail 690) may be defined in the profile of retention bracket 610 by the top surface of first arm 614, retaining hook 622, and elastically deflectable tab 624. Retaining hook 622 may define first hook channel 633. Moreover, during installation and as shown in FIG. 6A, rail 690 may be partially and or pivotally installed in a portion of channel 621 such as, for example, first hook channel 633. Rail 690 may also engage tooth 636 defined in linking portion 620 of first arm 614 to rock or pivot into engagement with retaining hook 622, the first rail stop 611 and elastically deformable tab 624. More specifically, second engagement tab 696 may be pivot it into engagement with retaining hook 622 as shown in FIG. 6B. Rail 690 may also rock or pivot on tooth 636 and engage and deflect elastically deflectable tab 624. More specifically, first engagement tab 694 may contact and deflect elastically deflectable tab 624 such that rail 690 and first engagement tab 694 rotate past elastically deflectable tab 624. In this regard, first engagement tab 694 is disposed beneath elastically deflectable tab 624, “locking” or “clicking” rail 690 into retention bracket 610.
In various embodiments and with reference to FIG. 7 , roof attachment system 700 (e.g., roof attachment system 700-1, roof attachment system 700-2, roof attachment system 700-n) may be deployed in several installation locations along a piece of rail 790. The spacing between the various roof attachment system 700-1, roof attachment system 700-2, roof attachment system 700-n may be determined based on the construction of the roof, local code, engineering analysis and/or or any other suitable method. Moreover, when rail 690 is installed in roof attachment system 700-1, roof attachment system 700-2, roof attachment system 700-n, rail 690 may bind to prevent sliding of the rail. This binding may be caused by the interference fit between the retention bracket (e.g., retention bracket 210 and first tooth 236 - as shown in FIG. 2A). This may aid in the installation of the rail on a roof.
